2003 Nautique 206 - Will Not Crank

[jenglemn]

Hello,

I have a 2003 Nautique 206 (PCM EX 330 GM) and it will not crank. The battery is now new. The starter works and is new, can be jumped, and the relays are all new and good. The lanyard switch is good as the dash pod gauges lights up after the code is entered. The Alternator is now new. The neutral switch is good. When jumping the starter, it will not start. When I push the start button, I can hear the relay clicking, but no starter. Where should I go now? Thanks!

Any chance there is water in the cylinders? If so, you may be hydrolocked.

If there is any chance of that, pull the spark plugs before you try cranking it anymore. Otherwise you may ruin the engine trying to start it.

When putting 12 volts on the starter solenoid (jumping it), the starter and motor rotate. When trying from the "Start" button on the key pad the relay clicks softly but no starter engagement. I have verified that the lanyard switch is operational. The neutral safety switch is also operational. When jumping the starter with the dash pod fully activated there is no spark or fuel pressure.

So the motor will turn over but won't start when jumped. This is understandable as you are jumping the relay and the start circuit is not on. This would tend to tell you that you have a voltage drop issue between the battery and the start circuit.

It sounds to me like you have a bad ground or power cable which is not uncommon on a 25 YO boat. I would start at the battery and really look at the connections. Corrosion at the battery can occur under the jacketing and move up the cable. I'm also no fan of lead battery connectors. I've found them hard to diagnose and tend to deteriorate over time. From there I would go to the other end and check the ground at the block and the hot at the starter the same way. If still no joy it would be time to check voltage at the relay and see if you're getting full voltage or if there is a voltage drop somewhere.

Hello, I am not jumping at the relay. I am supplying power to the trigger at the Starter.

I don't suppose you have a spare keypad around, do you? I wonder if something in the keypad has failed.

I do not have a spare keypad. Does anyone know where I can source a good one for testing purposes?

I would suspect the only testing device would be one purchased from NP. I didn't see anything on flea bay.

I have a spare that will fit your boat. I can send it out to you tomorrow. PM me your address and I'll get it ready to go. If it fixes the issue, I'll sell it for $200, or you could buy a new one from NautiqueParts. If it doesn't fix the issue, just send it back to me. I kind of like having a spare one around.
